TYPE-SETTING APPARATUS.

SPECIFICATION formingpart of Letters Patent No. 626,758, dated June 13, 1899. Application filed February 17,1898. $e1'ial No. 670,612. (No model.)

To aZZ- whom it may concern! Be it known that I, CHARLES D. HUGHES, a citizen of the United States, residing in New York, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-Settin g Apparatus, of which the following is a Specification sufficient to enable others skilled in the art to which the invention appertains to make and use the same.

My invention relates to the class of typesetting apparatus in which the types are forwarded from the lower ends of type-containing channels by means of pushers actuated by key-levers and connections.

The main object of my invention is to relieve the hand of the operator of the greater portion of the weight or strain consequent upon the forwarding of a type and at the same time quicken the operation without losing control thereof.

The invention consists, essentially, in interposing between each key-lever and the bell-crank with which the pusher is connected a supplementary segmental lever so arranged in conjunction with a constantly rotating wheel or roller that when the key-lever is depressed the said supplementary lever Wlll be brought in contact with said rotating surface, thereby relieving the hand of the operator of a greater portion of the resistance to be overcome and facilitating the operation of forwarding the type. The delicacy and quickness of action thus attained is a matter of great practical importance, enabling the operator to set more type in a given time with less fatigue. Furthermore, this result is contributed to by the fact that the operator does not lose control of the actuating device, the intermediate lever and roller acting as auxiliaries, but the finger of the operator still remaining in control until he feels the completion of the stroke and releases the key-lever. In the accompanying drawings I represent parts essential for carryingout my invention practically, although I do not wish to confine myself to the identical form and construction of parts shown, since it is obvious that modifications may be made in both configuration and arrangement without departing from the spirit and intent of my invention.

Figure 1 is a diagrammatic representation the device.

of mechanism employed in effecting the forwarding of the types from a type-containing channel, all the non-essential parts of the apparatus being omitted. Fig. 2 is a rear elevation of a portion of the apparatus, showing a plurality of intermediate levers, (K50.

A represents a type-channel, the type in which rest upon the floor or platform a, from which they are forwarded by the pusher P until they are free to drop upon the inclined plate 0 in the usual way. The inner end of the pusher P is connected with one arm of a bell-crank L, the forward end of the pusher passing through the ferrule f and a spiral spring 5 being interposed between the ferrule and the shoulder s on the rear end of the pusher-rod, which spring tends constantly to hold the pusher and pusher-rod in their retracted position, with the upper arm I of the bell-crank lever L resting against the back rest B, as shown in solid lines in Fig. 1, the

forward thrust of the pusher, 850., bringing said upper arm Z into contact with the front rest 15, as indicated in dotted lines in said figure.

The lower or shorter arm Z of the bellcrank lever L is connected by the rod R to the intermediate lever I, pivoted at i to a toggle T, in turn pivoted at t to a stationary part of the frame.

The intermediate lever I is formed with a segmental bearing 1, adjoining which is situated a roller J, which is made to rotate continuously during the use of the apparatus in the direction indicated by the arrow shown in Fig.1. A buffer or rest B is preferably provided to sustain the lever I in its normal position.

The intermediate lever I is connected with the key-lever K by another connecting-rodR, the two rods R R representing the ordinary connecting-rod, with the intermediate lever I interposed between the halves thereof.

In order to limit the movement of the toggle Tin one direction, a stop t is arranged to intercept the extension 2? of the toggle, as shown in Fig. 1, or obviously the same result may be attained by a stop arranged to limit the motion of the body of the toggle or to limit the motion of the intermediate lever I direct or of any of the adjoining movable parts of Furthermore, the connectingrod R may be pivotally connected to the toggle T, if desired, although I prefer to'pivot it directly to the intermediate lever I, as I thereby maintain control of the said lever I more eifectually-that is, the key-lever K is rendered more sensitive in action. A special feature of construction in this connection consists in providing the rod R with right and left hand screws r r at its eXt-remities'for engagement with female screw-threads in the coupling-nuts r r. By this means I provide a quick and convenient as well as delicate adjustment for and between the parts.

The operation of myimproved device is as follows: The outer end of the key-lever K being depressed by the finger transmits its motion through the rod R to the intermediate lever I, the toggle T yielding. As a result the segmental part I of the intermediate lever I is brought into contact with the friction-surface of the roller J, which thereupon rocks the said lever over into the position shown in dotted lines in Fig. 1, thereby rocking the bellcrank lever L through the medium of the rod R and effecting the advance movement of the pusher P. The completion of the forward stroke of the pusher will be instantly felt by the operator, who then releases the key K and the parts assume their normal condition.

The motion necessary on the part of the keylever K in order to bring the segmental portion I of the intermediate lever I into contact with the roller J is comparatively slight, after which motion, as will be readily understood by a comparison of the dotted lines in Fig. 1 with the solid lines, the roller J takes up and effects the far greater degree of eX- tent of motion. This motion, however, on the part of the roller J is not absolutely positive,-

so that if the operator desires to forward the pusher he can do so by depressing the forward end of the key-lever K slowly, there being sufficient slip or looseness between the roller J and the segmental portion 1 of the has never heretofore been attained so far as I am aware. It represents a gain of practi cally two-thirds of the motion as compared with older keyboards and a corresponding saving both in time and energy expended by the operator.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In type-setting apparatus, the combination witha type-pusher and key-lever, of a rock-lever attached to the pusher, a rod connecting said rock-lever with an intermediate lever, said intermediate lever formed with a segmental bearing for contact with a rotatable roller, said rotatable roller and a rod connecting said intermediate lever with the keylever, the whole arranged and operating substantially in the manner and for the purpose described.

2. In type-setting apparatus the combination with the pusher P, rock-lever L, rod R, intermediate lever I, having segmental section I, rotatable roller J, toggle T, rod R, key-lever K, the whole arranged and operating substantially in the manner and for the purpose described.

3. In type-setting apparatus the combination with the pusher P, rock-lever L, connect-'- ing-rod R, formed with the right and left hand screws 9, 7*, engaging with a female screw in the couplers r 1 the intermediate lever I, the roller J, the rod R, and the keylever K, the whole arranged and operating substantially in the manner and for the purpose described.
